Milk microbiology. In addition to being a nutritious food for humans, milk provides a favorable environment for the growth of microorganisms. Yeasts, moulds and a broad spectrum of bacteria can grow in milk, particularly at temperatures above 16°C. Microbes can enter milk via the cow, air, feedstuffs, milk handling equipment and the milker.


A given mill may operate successfully in more than one class: a hammer mill may be used to prepare a 16-mesh granulation and to mill a crystalline material to a 120-mesh powder. The mills used for size reduction of the granules can be divided into two primary categories based on the energy input into the process.

When identifying milk quality issues, a standard plate count (SPC) test isn't enough. Elevated SPC could indicate dirty equipment, poor cooling, contaminants from the environment or a variety of other issues. While an SPC test can tell you when bacteria levels are high in raw milk, it can be difficult to identify where the problem is coming from.


Since the level of the microbial quality of raw milk should be increased, we investigated and developed convenient methods of determination of psychrotrophic bacterium counts in the last years (Urbanová et al., 1988; Urbanová, in print): these methods should facilitate the reasonable control applying an expeditious procedure.
